Hylomar never dries completely (non- setting) which makes it inappropriate for long term case sealing. If used as a case sealer, you might get lucky but it's a lot of work to reseal a case so hoping to get lucky seems vacuous to me.
For racing or sport engine that are disassembled on a regular basis it is fine.
The product is basically the same consistency as Curil T and should only be used in similar applications.

In the case of weeping chain box gaskets that had 574 thinly applied a simple retorque may cure your weeping issues.
